1. Pick a random backdrop (note that the backdrops are already named 1, 2, and 3 for you). 2. Ask the user which animal belongs in that environment. 3. Check to see which animal the user entered, and switch the costume to that animal. If we don't have that animal as an option, say "Sorry, that animal can't live here!" 4. Wait for two seconds and switch to a random backdrop. 5. Repeat steps 2-5 so the user can play forever!
